Amy Winehouse’s fans will never hear at least 12 of the late singer’s recordings, because she banned them from release before her death. The Back to Black hitmaker’s posthumous third album, Lioness: Hidden Treasures, hits shelves next month, and bosses at Island Records UK have revealed they have enough material to fill a fourth record.

However, Winehouse insisted certain songs should never be released, and label chief Ted Cockle has vowed to honour the star’s wishes.
